Description

The invention relates to a power system and can be used for autonomous heat supply of industrial and domestic consumers with thermal energy.

Known steam generator containing an evaporation and heating chamber. In the lower part of the evaporation chamber there is a grate with a heat storage nozzle onto which water is sprayed. The generated steam is diverted to the consumer. (USSR AS No. 1778438, F22В 27/14, 11/30/1992) [1].

A disadvantage of the known steam generator is the complexity, bulkiness of the structure and low efficiency in operation.

Closest to the proposed invention is a steam generating device comprising a gas turbine engine, aggregated with a steam generating device, feed water supply device and steam outlet to the consumer. (USSR AS No. 311088, F22В 27/06, 08/09/1971). [2].

The disadvantage of the closest analogue is the complexity, cumbersome design and low efficiency in operation.

The technical problem solved by the invention is to increase the efficiency of the steam generator in operation while simplifying its design.

The problem is solved in that in a steam generator containing a compressor, for example an axial one with a drive, for example an electric motor, a steam generating device and feed water supply and steam outlet devices to the consumer, the compressor is made in a sealed enclosure, for example, its inlet - intake is sealed with a removable cover. The feed water supply device has the form of a throttle, for example a valve and a spray, for example mechanical, which are made with the possibility of controlled, for example, manually feeding and spraying feed water to the compressor inlet. In this case, the steam generating device was made using the compressor's ability to create a vacuum in the casing — at its inlet, to convert the feed water to water vapor, to compress the resulting steam with an increase in its temperature, for example, to 100 ° C and to discharge the resulting steam to the consumer through the outlet pipe.

The invention is schematically shown in the drawing.

An example of the implementation of the proposed solution.

The steam generator comprises a compressor 1, for example an axial one, made in a sealed housing 2, for example, sealed with a removably fixed cover 3, a drive of the compressor 4, for example an electric motor. The feed water supply device has the form of a throttle 5, for example, a valve and a spray 6, for example mechanical, made with the possibility of manually controlled, for example, supply and spraying of feed water to the compressor inlet. In this case, the steam generating device is made using the compressor's ability to create a vacuum in the housing, at its inlet, to convert the feed water to water vapor, compress the steam with increasing temperature and supply the resulting steam to the consumer 7 through the outlet pipe 8.

The steam generator operates as follows.

To start the steam generator, the drive 4 of the compressor 1 is turned on. The operation of the guides and rotor blades, for example, the axial compressor 1 in the sealed cover 3 of the body part 2, creates a vacuum at its inlet. The feed water supply device through, for example, manually controlled by the throttle 5, delivers and sprayes through the sprayer 6, for example, return water from the consumer 7 to the compressor inlet 1. Due to the rarefaction in the sealed cover 3 of the housing 2 of the compressor 1, the sprayed water turns into water vapor. Then the water vapor is compressed by the compressor 1, for example, to 03 MPa, its temperature rises, for example, to 100 ° C, and then the steam is discharged to the consumer 7 through the outlet pipe 8.

The proposed steam generator is simple to manufacture, highly efficient in operation. It can be widely used for autonomous heat supply of industrial and domestic consumers with thermal energy.
